Creating file systems
Refer here also to the manual "POSIX Basics".
Authorization: The BS2000 privilege TSOS and root authorization are required for the creation and administration of POSIX file systems.
File systems are created by using the POSIX installation program, menu: Administer POSIX file systems. After initial installation of POSIX has been completed, the POSIX file tree in its minimum configuration contains the root file system / and the file system /var, each in their own separate container file. Further file systems can be created as required.
When a new file system is created, the size of the container file is also defined.
Storing the file systems
The entire POSIX file tree is stored in one or several container files (these are BS2000 PAM files). The container files reside on disks (PVS, Public Volume Set).
Naming conventions
The names of POSIX files may have a maximum length of 1024 characters. This length includes the names of the directories, the file name itself, along with the delimiting slashes.
